Yep the atom board is great for a nas/backup and you wont have to spend nearly as much as you think. My no longer being used atom board has wifi, wired, and 3 sata slots. Never had any issues streaming from it or manually backing files up to it (i dont trust auto back ups). Definitely recommend it. You can go with the older generation such as mine (which is for sale in bst) or you could go with the new generation (though there isnt much difference between the two really, just chipset)
